Are you sure you're entering the right bank numbers in your sequencer? The ordinary drum bank number is 16256, and if you enter this and then click on the patch list you should find the ordinary drum kits up near the top of the list. For the special drum kits (SFX, etc.) the bank number is 16128 and, once again, the SFX kits are mainly to be found at the top of the patch list.
The banks and patches for the non-drum sounds are listed in the manual, starting on page 87. It's not clear what numbers are supposed to be selected from this list, though, if you haven't had to plough through one of Yamaha's needlessly complicated MIDI implementation charts before.
In fact, the numbers you want are in the column labelled LSB (0-127) and the number right next to that, in the column labelled MIDI program change (1-128).
For example, the first voice in the list is the Power Grand piano, and you should be able to see from this that the bank number you should enter is 113 and the voice number is 1. There's one more annoying detail to be aware of: You have to deduct 1 from the MIDI program change number in order to get the right sound. Therefore, to select the Power Grand Piano, you should select bank 113 and program change 0, instead of 1. One more example from the same page: The first organ sound (Sweetness) is selected by typing bank 117 and voice number 4.
You should be aware that many of the banks used by the MM6 have barely any voices within them, so there will be long, empty stretches in certain banks.
(I've only had my MM6 for about three days, and I spent most of that time getting these bank and patch change numbers sorted out!)
One other thing: Someone mentioned just selecting the voices from the instrument and then recording the sound to audio (I think that's what they said). This isn't going to be a useful way of working. You have to get the pattern data into a sequencer before you can do anything really useful with it. The drums on the MM6 are a bit flat and upfront, and in order to process the sounds properly you're going to need different
drum instruments on separate tracks, so you can add, say, reverb to the snare, but leave the kick dry. Also, if you want to change the instruments used by the patterns, they have to be in a sequencer first.
Then you'll be wanting to send initialising information from the patterns too, but I don't have time to go into that right now.
I hope I didn't misunderstand the question, and that this might be helpful in some way.
